BED-SPRING.

Application filed March To all whom it ma/y' concern:

Be it known thatl, WILLIAM W. VnvoENT, a citizen of the United States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have'invented certain new and useful Im rovements in Bed- ?prings, of which the flillowing is a specifica- My invention relates to springsfor beds, its object being to provide a spring of this kind which will have rigid head and foot bars at the top of the upright spiral springs;

suitable connections joinin the springs to the bars, thereby securely holding the former in place and preventing them from tipping out of their proper positions even after considerable usage. Bed springs without such stren 'thening and sustaining head and foot bars have been known'for years and have been com ressed vertically into com paratively smal space during transportation, several of such compressed or compacted s rings occu ying no more space or volume t an a sing e expanded spring, that is, one in normal condition.

The real or main object and pur ose of my invention'is to combine the goor and valuable features of each of these kinds of bed springs in my improved construction.

The preferred or most desirable form of my novel bed spring has rigid andfixed head and foot bars of the character and for the purpose described, held-in place by detachable or colla sible braces, the latter when a detached or folded eliminating the rigid or fixed features of the bars and permitting the bed spring as a whole to be compressed for shipment: None of the parts of the braces or spring are wholly detached or removed from the structure, consequently there is no danger of the loss of any of the essential parts while in transit.

On the accompanying drawings which form a part of this specification, and to which reference should be made in connection with the following detailed description, I have illustrated the preferred embodiment of my invention, and in the various views like ref erence characters refer to the same parts.

On these drawings,'-Fi ure 1 is a broken plan view of my improve bed springs; Fig. 2 is a side elevation of the structure shown in Fig. 1', showing the spring in expanded or operative condition; Fig. 3 is a side elevation of the portion of the spring on an en- Specification Letters Patent.

This construction of bed spring has a substantiallg rectangular base or bottom supporting rame composed of the two end bars 10, 10 and thefair of longitudinal side bars 11, 11 dispose on edge and suitably connected together at their ends. This bottom supporter frame 1s also provided with a plure 1 ty of similar transverse bars 12, 12 dieposed on edge and connected at their ends to the side bars 11, the lower ends of the considerable number of spiral com ression springs 13 resting upon these bars, W ich are prevented from spreading apart by the longitudinal spacing rods or wires 14. At each end of the structure, and disposed substantially in the plane of the top surfaces of the coil compression springs, is a pair .of parallel angle bars 15, the ends of which are connected together by the longitudinal marginal rods or wires 16 each equi ped with a pair of coil tension springs 17. unning longitudinally of the bed spring, and connected at their opposite ends to the inwardly-disposed horizontal flanges of the end bars 15, 1 provide a number of tie or binding wires 18 which assist in maintaining the top ends of the springs 13 in position, being aided in this function by the considerable number of transverse tie wires 19. To each terminal portion of the angle end bars 15 l rivet or otherwise fasten at 20 one end of a brace bar 21 which is bent to an angle of 90 degrees, as is clearly indicated in Fig. 3, its free end having an inwardly-ex-tended open-mouth slot 22 which in the normal condition of the spring receives an outwardly-projected abutment pin 23 on the outer face of the adjacent longitudinal side bar 11 of the bottom frame, as is clearly illustrated in Fig. 2. Near the center or middle portion of each angle end bar 15 I rigidly attach at 24 the upper end of a similar flat inclined brace bar 25, whose lower end 26 is bent downwardly, as indicated in Fig. 5, and provided with an 0 nmouth slot 27 which accommodates an a utment pin 28 fastened to the face of one of the transverse bars 12. It will be ap arent, therefore, that when the braces 21 an 5 are in the operative position indicated in Figs. 2

and5, the end angle bars 15 are held in such osition that they are prevented from movescape the pins to rigidly and mg inwardly or toward each other. In order fixedly hold these end angle bars 15 in position and dprevent their downward movement tower the bottom spring sup orting frame, I pivot or hinge at 29 at eac end of the side bars 11 a supporting bar 30 notched at its free end on one-side at 31 so as to hook over and accommodate a pin 32 on the outer face of the adjacent brace bar 21. These supporting bars 30 when in operative position are disposed substantially-vertically, as indicated in Fig. 2, and they, in conjunction with the braces 21 and 25, secure and hold the end bars 15 immovably in osition. Hinged or pivoted at intervals a ong the outer surfacesof the side bars 11 are a lurality of g sup orting hooks or rackets 33 a apted to 00k over or bear upon the'side ralls of the bedstead, these hooks or brackets being'in vertical position,

as shown in Fig. 2, when in operative condition.

In order to put this bed spring into such condition that it maybe compressed vertically into small space, so that it and a number of others in the same condition may be crated so as to,occupy comparatively small volume, the spring supportmg hooks 33 are turned on their hinge or pivot pins 34 to bring them alongside the outer aces of the longitudinal side bars 11, as indicated in Fi 3. The vertical supporting bars 30 are t en swung outwardly sufliciently to 32 which have previously been fitting in the open-mouth slots 31, and are then swung inwardly so as to lie along the outer faces of the bars 11, the angle bars 15 and inclined braces 31 being lifted sufficiently whereby during this inward turning of the supporting bars 30 their free ends will 'escape the pins 32. Then the end angle bars 15 are ushed outwardly sufficiently to free the ower ends of .the braces 21 from their cooperating ins 23,

there being give or elasticity enoug m the spring fabric to permit this movement. The central braces 25 are lifted so that their lower notched-ends no longer engage the supporting pins 28. When the parts are in this condition the entire bed spring may be compressed to the condition shown in Fig. 3, the outer braces 21 restingupon the top edges of the side bars 11. As is a parent, a number of these bed s rings in t eir compressed condition may e crated and transported and occupy'but little if any more volume than that taken up by one of the springs in expanded operative condition.

When the bed springis uncrated it is permitted to expand, the end bars 15 are sprung outwardl sufficiently to permit the lower ends oft e braces 21 and 25 to, engage their corres onding supporting pins 23 and 28, and t en the supporting bars 30 are swung up and hooked on to the pins 32 of the braces 21, that is, the slots in porting ends receive these pins. Before t e spring can be placed upon a bed, however, it is necessary to turn the supportinghooks or brackets 33 on their hinge pins 34 into vertical and operative osition. 3

To those skilled in t 's art it will be ap-;

parent that by my improved construction I secure all the advantages inherent to a bed spring with rigid end bars, and at the same time my improved spring possesses the benefit of being ca able of compression for shi ment. It wi be observed that none of the parts of the collapsible or foldin braces for the end bars are wholly detacliable from the spring, whereby there is no possibility of their being lost or misplaced during transportation.

To those skilled in this art it will be apparent and obvious that .this invention is not restricted to the recise structural features shown and described, but that the latter may be modified within wide limits without departure from the substance and essence of my invention, and without sacrificing any of its benefits and advantages.
